The IWM-MB4 is an integrated module that can be used with the Woltmann WDE-K50 line of water meters to transmit consumption data over a cable M-BUS network.
It is simple to install and set, and in addition to providing data on current consumption, it enables the detection of potential water leaks downstream of the meter, prolonged operation at maximum flow rate (Q4), and many sorts of attempted meter fraud.
The application is immune to the vibrations of the pipes thanks to the employment of an inductive target in the meter dial, which also eliminates the potential of magnetic fraud.
